Motivated by the work of Salvetti and Settepanella [24, Combinatorial Morse theory and minimality of hyperplane arrangements, Remark 4.5], we give a purely combinatorial description of a class of discrete Morse functions having a minimal number of critical cells for the Salvetti complex of any linear arrangement. We start by studying certain total orderings of the cells of shellable regular CW-...

The article presents the results of research on modified steel fiber-reinforced concrete and shows expediency their use to increase effectiveness fortification protection structures against shock loads. It was established that according tests compressive strength (fсm = 79.4 MPa) tensile during bending (fс, lf 7.4 MPa), can be classified as high-strength (strength class C 50/60) rapid-hardening...
